Seedance 2.5
Seedance 2.5 is ByteDance's video model for long takes. It makes clips of 4 to 30 seconds with sound from text, a first frame or up to 50 reference files, and it can also edit or extend a clip.
What Seedance 2.5 is
Seedance is ByteDance's family of AI video models. Seedance 2.5 is the newest one, and the one that makes the longest clips: up to 30 seconds in one take, with generated sound.
What it is good at
- Long takes: one generation runs up to 30 seconds, so a scene does not have to be stitched together from short clips.
- Reference control: pictures, video clips and audio can all guide the shot, and you point to them in the prompt as @Image1, @Video1 and @Audio1.
- Sound comes with the picture: effects, ambience and lip-synced speech are generated together, and you can switch the sound off.
Honest limits
- The shortest clip is 4 seconds.
- Image to video follows the shape of your picture, so the aspect ratio setting does not apply there.
- Reference videos and audio clips must each be 1.8 to 30.2 seconds long, and all reference files together stay at 50 or fewer.

Prompts to try on Seedance 2.5
Copy a prompt, or press Try it to open the generator with the model and the prompt in place.
A woman in a yellow raincoat walks through a night market after the rain. The camera follows her from behind, then circles to her face as she tastes a skewer and smiles. Neon signs reflect in the puddles. Soft chatter and sizzling.
Makes: A 10 second follow shot that ends on a close-up, with market sound.
A young chef with a shaved head plates a dessert in a small, bright kitchen. Slow push-in on his hands, then a cut to him serving it to a guest, who says "Oh, this is perfect." Warm light, quiet restaurant sound.
Makes: Two beats in one take, with a spoken line the model lip syncs.
An elderly man in a green cardigan feeds pigeons on a park bench in autumn. Leaves fall around him. The camera rises slowly over the trees to show the whole park at golden hour.
Makes: A calm reveal that starts close and ends wide.
Two sisters in matching red coats build a snowman in a sunny schoolyard, laughing. They put a scarf on it, step back and cheer. Handheld camera, bright winter light, crunching snow.
Makes: A cheerful 8 second scene with ambient sound and no dialogue.
A girl with a blue backpack runs for a yellow tram, jumps on as the doors close and waves to her friend on the platform. Tracking shot from the street, morning light, bell and engine sounds.
Makes: A chase beat with a clear start, middle and end inside one clip.
A baker pulls a tray of golden croissants out of an oven, steam rolling over the camera. She sets one down in front of a child, who takes a huge bite. Close-up, warm tungsten light, soft music.
Makes: A food close-up with steam and a small reaction.
A boy in a paper crown stands on a hill at sunset and launches a kite. The camera starts at his feet and tilts up to follow the kite into an orange sky. Wind and distant laughter.
Makes: A simple tilt-up that shows the model's sense of space.
@Image1 sits at a cafe window and looks up as @Image2 walks in and waves. Medium shot, rain on the glass, warm light, soft jazz.
Makes: A reference to video shot with two named pictures (add your own pictures in the generator).
